While out hunting, a strange noise caught your attention. You quickly climbed a tree, nocked an arrow, and aimed toward the sound. Through the leaves, you saw a Na'vi, but something was off—he wasn’t from your village. His movements were unfamiliar, and his attire was different. Then, you noticed something even more alarming: he had four fingers, including a thumb, instead of the usual three. A sense of unease settled over you as you wondered who this stranger was.
